Problems solved by technology

However, according to the literature, all ultra-high-strength cement-based composite materials are basically gray or gray-black. Although MDF can be made into various colors and shapes, the production process is complicated, the cost is high, and the performance deteriorates after being exposed to water, so it is difficult to popularize. use

Abstract

The invention relates to a cement-based composite material product and a preparation method thereof. A white or colored cement-based composite material plate with the super-high strength is characterized by being compounded by white cement, slag powder, medium sand, fine powder, active gap filler, mixed fiber, water-reducing agent, pigment and water, wherein the plate comprises the white cement, the slag powder, the medium sand, the fine powder and the active gap filler in parts by mass: 847-1016 parts of the white cement, 203-254 parts of the slag powder, 914-931 parts of the medium sand, 203-254 parts of the fine powder and 203-254 parts of the active gap filler; the adding amount of the mixed fiber is 1.5-2.5 percent of the total mass of the white cement, the slag powder, the medium sand, the fine powder and the active gap filler; the adding amount of the water-reducing agent is 0-2.0 percent of the total mass of the white cement, the slag powder and the active gap filler; the adding amount of the pigment is 0-5.0 percent of the total mass of the white cement, the slag powder and the active gap filler; and the mass ratio of the water to the white cement, the slag powder and the active gap filler is in a range of 0.16-0.18. The white or colored cement-based composite material plate with the super-high strength, provided by the invention, has the advantages of better mechanical property and decorative property, and long decorative effects.

Description

technical field [0001] The invention relates to a cement-based composite material product and a preparation method thereof. Background technique [0002] Cement-based composite materials are composite materials composed of Portland cement as the matrix, various fibers, polymers, whiskers, etc. as reinforcements, adding fillers, chemical additives and water through a composite process. It has improved performance compared with general concrete, especially impact resistance and flexural performance. The cement-based composite materials that can achieve ultra-high strength mainly include the following categories: macro-defect free cement (MDF), high-density cement-based homogeneous system (DSP), high-performance concrete (HPC) and reactive powder concrete (RPC) that have appeared in recent years. Wait. There are many research documents about them, and there are also many open patents, such as invention patents on reactive powder concrete: CN200710044727 (a kind of high-streng...
